The size of the image increases as the lighted candle is brought closer to the mirror.
A er a point, the size of image becomes larger than that of the object. This shows
that the image is real. inverted and magnified.
C :

Move the candle very close to the mirror.

Virtual, erect and magnified image
Observa on:
You will find that the image is virtual, erect and magnified.

Formation of Images by a Convex Mirror
Let's understand the nature of image formed by a convex mirror by

performing the following activity.

Activity-2 Aim: To study the nature of image formed by a convex mirror.
Materials Required: A convex mirror, a stand to fix the mirror in place, a cardboard,
Experiential Learning
a stand to fix the cardboard, a white sheet of paper and a candle

Procedure:
• Repeat the previous ac vity using a convex
mirror in place of a concave mirror.
• Observe the nature of the image formed.
Observa on: The image formed by a convex mirror
is virtual, erect and smaller in size that the object.
Virtual, erect and diminished image
